5. Information about your pumpCompressed air, pumped down the well, is mixed with
water in the discharge pipe as very fine air bubbles
by the air distributor installed at the end of the air
pipeline. The air-water mixture has a lower density
than water in the surrounding water column and so
the air-water mixture rises in the discharge pipe and
eventually flows out of the pipe. The outlet from the
discharge pipe should never be connected to a pipeline
running over a long distance since this will cause
hammering as the water is ejected due to large air
pockets formed during horizontal travel of air-water
mixture. The flow of water is not continuous and
delivery of water depends on the yield and water level
in the bore well.
Taro Borewell Compressors are designed for pumping
water from deep wells of up to 400 feet. Borewell
Mono compressor pumps are designed for domestic
purpose of pumping water from bore wells. These
Borewell Mono compressor pumps are coupled
directly to the motor for higher operating efficiency.
Our compressors are sound in design and robust in
construction and are manufactured and tested to
high standard of excellence. They give satisfactory
service with proper installation and normal routine
maintenance.
TABLE 1, shown below, indicates the range of Borewell Compressor Pumps offered by us. Selection is based on the

this precaution could lead to electrical shock, short circuit or fire.
Fig. 9 Pulley positioning and alignment
Pulley positioning, alignment and belt tensioning
It is essential to ensure the compressor pump has an adequate degree of protection from dust and water. Ensure
that the compressor pump has no obstruction around it as this can reduce the free circulation of cooling air. The
motor drives the compressor through a belt drive. The motor pulley and compressor fan pulley must be properly
aligned. The motor and compressor shafts must be parallel to each other. The belt should not be overly stretched
or tensioned. To assemble the pulley on the motor shaft, insert the pulley halfway up the keyway manually.
Intense hammering should be avoided during fitting of pulley as this process can result in damage to the raceways
over a period of time.
Refer Fig. 9 for pulley positioning and alignment.
Belt tension is provided by adjusting the center
distance between the compressor and motor. The
compressor is firmly bolted to the base plate, while
the motor is moveable. Use the bolts to adjust
the position of the motor and therefore the belt
tension. If the belt tension is slack, the belt can slip.
If the belt tension is too high, the bearings can get
overloaded leading to premature failure.
OMBC001A 21 2020.01
Refer to Fig. 10 for tensioning the belt:
The assembled compressor with fan and the rails for mounting of the motor are located on a
base plate.
The base plate is fixed to the concrete foundation using the four foundation bolts.
Mount the motor and clamp it to the rails using the 4 sets of bolt, nut and washer.
Mount the Motor Pulley on the motor shaft and ensure that it is aligned with the fan pulley.
Install the V-Belt to pass over the two pulleys.
Using the pre-tensioning bolt with nut, push the motor away from the compressor till the belt is
properly tensioned. Tighten the nut to prevent the bolt from loosening during operation.
Now clamp the rails to the base plate using the 4 sets of bolt with washer and nut.
